16 Claims.

This invention relates to improvements in a silk reeling lapparatus and particularly to a machine for automatically supplying silk filaments from cocoons and twisting the laments into a thread which is thereafter Wound onto bobbins, spools 4or the like.

One of the objects of this invention is to provide a better control of the cocoons as they are operated upon by the apparatus.

Another object of the invention is to provide an arrangement so thatthe cocoons and the lilaments drawn therefrom will not stick to thematerial of which the apparatus is made.

Another object of this invention is to so con'- trol the flow of water in which the cocoons rest that they will remainseparated that the laments may be more easily drawn therefrom.

Another object of the invention is to provide Aa pick up wheel for a filament to be added to the twisted thread which will be so arranged that injury` to the operator will not occur if the wheel is contacted.

-Another object of the invention is to provide an easy way of removing for cleaning the pick up Wheel for the laments even though the same is in operation.

. Another object of this invention is to provide' a more convenient arrangement for removingthe exhausted cocoons from the apparatus.

Another object of this invention'isto improve the traverse guide for the silk thread to be reeled.

Another object of the invention is to provide a control for the cocoons and filaments drawn therefrom by which the Work will not becomerinjured as drawn from `reeling position.

With these and other objects in view,the invention consists of certain novel features of construc-` the reeling basin and the rear endof the supplyv basin for the reserve cocoons;

The present improved silk reeling machine comprises in general a supply basin for reserve cocoons o f raw silk and a reeling basin into which the cocoons are fed individually by automat-ic transferring means and from which location the silk filaments are drawn off from aplurality of cocoons which` are twisted and reeled. Means are provided for circulating-warm watery through the two basins to float and degum the cocoons whereby to facilitate the releaseof the laments therefrom together with means for ejecting the denuded or spent cocoons fromth'e reeling basin after the silk has been exhausted therefrom. A pickup wheel is'provided for engaging the lila-V ment of each cocoon as it is'transferred from the supply basin to thereeling basin' which pickup wheel twists the filament about the thread previouslyformedand Vat the same time breaks the filament so'that but a short endis cast on. A suitable'means is "provided for gaging the thread that is formed' and should the thread become below sizemechanismis actuated whereby additional cocoons from thesupply basin are transferred to the reeling .basin until the thread arrives at the size desired. The action is sufficiently slow so that each lament arrives at the gaging 5751V point prior to the movement of another cocoon from the supply basin to the reeling basin. Should the thread become broken the spool upon which the thread of that unit is wound will become declutched from its driving mechanism. The apparatus consists of a plurality of units each of which operates individually as to the supply of cocoons or filaments to make up the proper size thread although certain xedly operating parts of the apparatus are all commonly driven from shafts extending throughout the length of the apparatus. The apparatus is supplied'in any desred number of units depending upon the size of the apparatus desired. A suitable detachable guide is provided to relieve the traverse bar from wear. The spent cocoons are collected in a tray which may be easily removed from the machine for discharge of these spent cocoons.

Referring to the drawings, there is aframe 'work designated generally l0 and consisting of a horizontal supportinglframe with vertical supports |2, I3 and I4. This frame work is of angle iron formation of sufficient size to provide the strength necessary. Upon the horizontal supports and on a bar I provide a supply basin l5 having a lip to extend beneath the bar, and which will contain a reserve of cocoons and a reeling basin designated generally l5 which is at an elevation just belowthe elevation of the supply basin as shown in Fig. 4' or 6. Below these two basins there is a reservoir l1 which contains water which is heated and circulated through the supply and reeling basins.v The water is pumped from the supply basin |1 (Fig. 1) to a chamber 8 (see also Figs. 6 and 18) which extends lengthwise of the machine and from which there are conduits to nozzles I9 (see Fig. 6) each of which extends in asupply basin iand has an opening directed toward the front of the machine so that water flowing from this opening will strike the front wall 2| of the basin l5 and will then reverse the flowv as indicated by the arrow 22 so as to flowtoward the rearrof the machine and in the direction of movement of the cocoons. By reversing the flow of the incoming water in this manner a circular whirling of the water is prevented which causes the cocoonsrto collect in groups. This arrangement assistsV in separating the cocoons although tending to move them in the direction of travel in which it iS desired they shall move.

Through all of the Supply basins there extends a shaft 25 (see Figs. 5, 6 and 13) upon which in each basin there is mounted a roll .26 over which there is trained a belt 21 of some liber material which belt also engages la, pulley 28 rotatably mounted upon an individual shaft 29 which is mounted in bearingsril having rods 3| extending therefrom through supports 32 with a spring 33 acting between the supports 32 and the bearings to move the shaft 29 away from the roll 26. Thus, as this belt is operated the shaft 29 is operated. Mounted upon vertical shafts 35 there are rolls 36 at either side of the belt 21 and in contact therewith which are covered as at 31 with. some non-metallic material such as'ber and which rolls are located to extend upwardly `above the surface of the liquid which is contained in this basin and provide a guide means for the cocoons in the basin. These rolls 35 being in contact with belt 21 are rotated by the movement of the belt 21. Guides 38 consisting of vertical walls converging as shown in Fig. 5 are also pivotally mounted on the shafts 35 below the rolls 36 which may be adjusted to direct the cocoons inwardly toward the belt 21.

A false bottom 40 in the supply basin I5 is provided With a lip 4| having an opening to receive the trunnion 112 for rockably mounting this end of the false bottom in the basin. A bracket 43 is secured to the bottom at a point spaced from the flange 4| and is also provided with an opening to receive a trunnion 44 mounted on bracket 45 extending upwardly from the bottom 45 of the supply basin to provide another pivotal mounting which'will be substantially axially aligned with the trunnion 42 for rocking the false bottom 45 about a horizontal axis extending in the direction of movement of the cocoons. The sides 6 of this false bottom are tapered inwardly toward the horizontal portion 41 thereof While this bottom is cut away as at 48 so as to receive the belt 21 in the space thus provided. Additional inclinations of this bottom are provided on either side as at 49 so as to assist the cocoons in being moved toward the conveyor belt 21. In order to rock this false bottom about the pivotal trunnions 42 and 44 I provide cams 55 and 5| (see also Fig. 7) on the shaft 29 so located that as one side of the bottom is raised the other side is lowered that a rocking motion may occur of the false bottom inthe liquid. Upwardly extending walls 52 as illustrated more clearly in Fig. '1 are also provided on this false bottom.

The cocoons which are shown in dotted lines and designated 53 are loaded into the supply basin I5 and the filaments 54 from each of the cocoons areV gathered and manually wound about the conical member 55 which is mounted on a shaft 56 rotated intermittently, as will hereinafter appear,r for tensioning the filaments. Guides 58 extend from the rolls 36 for conning the movement of the cocoons. The'reeling basin which is designated generally I5 is connectedv to the supply basin by an inclined member '65 having a cocoon conveying surface 6| with flanges 62 which surface is located at such an angle that should a cocoon engage it, it would slide down this member into the reeling basin designated generally I5. A brush 63 extends across the lower end of this member and will permit filaments of the silk from the cocoons to enter the brush although the bristles would prevent the cocoon itself from being raised upwardly due to a pull on the filament and thus acts as a stop to limit lifting the cocoons from the water level 64 in the basin. Water is discharged from the supply basin |5 which is at a level 51 through an opening 65 into the reeling basin and water is also discharged through the cutout portion 56 in the member 60 into this end of Vthefreeling basin. Suchwater as is so discharged will engage the baille 61 which extends upwardly from the bottom 63 of the reeling basin'and thus will permit the ow of water to be distributed and Will flow over the edge of this baii'ie 51 toward the discharge end 69 of the reelingbasin. Filaments from the cocoons being drawn upwardly over a guide 10 tend to move towardY the front of the machine and beneath the brush 63. However, as the cocoons become spent and the silk is com- Vpletely drawn therefrom, they will then float toward the back of the machine, at which point they Will abut against a rotatable wheel 1| which is located at the rear end of the reeling basin and nearly completely submerged in the water therein but for a slight portion of the peripheral marginal edge of the wheel whichis above the level 64. The wheel 1| has a plate 12 which extends generally on the curvature of the wheel and has one end thereof fastened to the periphamazon:

eryof the wheel and extendingoverY the peripheral surface of the. wheel with .thefree end thereof spaced from the wheel providing. anteccentric portion or relatively inclined surface on the said l wheel. At each revolution of the said wheel 1|. this plate 12 will engage and lift 'outo`f.the=waterK such cocoon which'may be in its path of movement and deposit the same on a hingedlymounted shelf 09', the free end of which'is turned up-` wardly and positioned in close adjacency'tofthe.

Wheel. Upon further movement-,of said wheel the fastened end of the plate 12 will pass beneathy the shelf and the inclined portion of said 'plate 12 in passing thereby will engage and. swing. saidi shelf to raise the same sufliciently to tilt the same 1 for the said cocoon deposited thereon to slide over the rear edge of the basin to drop onto the inclined chute 13 shown vin Fig. 4 fromwhich the said cocoon will move by gravity to the trough 15 at the front edge ofthe machine. This trough has handles 16 by which 'the trough may` be lifted to dump the spent cocoons fromthe machine. This chute 13 is perforated sothat any water flowing thereon will, drop into the supply reservoir I1.

Water from the supply reservoir ows into pipe 14 which connects with a pump (not shown) and which is delivered from the pump to pipe 18 and thence through pipe 19 to the chamber I8. Some heating means is provided for this Water which is usual in silk cocoon manipulation.

As a cocoon moves from the supply chamber l5 to the reeling cham-ber- |6,-its lamentA 54 which is fastened about the cone 55 swingsinto the path of a pickup wheel B0 shown in planV view in Fig. 1l and whichvconsists of a pair 'of arms `33| which each take the shape of generally a figure 6. These arms extend outward radially from the hub as at 82 and thencurve in a long sweep as at 83 leaving a collecting space 84,'between the arm and the hub and providing an arrangement so thatany vfilament which is.

picked up in this space 84 will be drawn in across the center of the hollow hub 85 of the Wheel. This hollow hub 85 frictionally engagesva hollow shaft 85 and is held thereon by spring ring 81 fitting in a groove 88 in the outer surface of this shaft. A spring 89 places some tension upon the wheel so that it will drive with the shaft. The shaft 86 is equipped with a pulley 90 having-*a groove 9| for receiving a round belt drive.

The thread which consists of an accumulation of filaments designated 92 (see Fig. 4). from' the reeling basin passes over the guide'10 supported by bracket 93 from the upright support I8 and through this hollow shaft 86 and thence upwardly as at 94 and extends over a guide pulley 95 supported at the end of arm 96 which .is pivoted as at 31 and weighted as at 98 and which serves as a stop motion device. The thread then extends from this guide 95 downwardly as at 99 over a fixed guide |00 and thence around thel portion 94 in a spiral pathas at |0I and thence upwardly as at |02 and through a gage mechanism designated generally. |03 and shown in greater detail in Figs. 18-21, thence under a guide.

|04 upwardly as at |05Y and over a traverse bar designated generally |06V tothe spool designated generally |01.

The gage mechanism showninig-reater .detail in Figs. 18-21 consists of a supportingbody |09-x carrying a supporting bllock of insulating material ||0 upwardly from which. thereL extends pairs of glass rods III and ||2as one 4pair be-l tween which the thread extends and I I3..and. I I4 as anotherV pair ybetween which thethre'ad also.y extends.. A guideroll ||5. is supported at one end of the insulating-block |IOL to guide the.

thread portion |02 thereover for elevatingit to proper height.. This :guide pulley I|.5 is. sup;y portedby bracket IIB which vis adjustably held' |22 and supported betweenl a pair-of ,arms |23 supported on the insulating block I0, by: means.

The. member |22 .is electrically connectedto 'the support|09 by means ofthe pivot pin|24 which is madeof a length to .extend beyond the arms |23v with one end of saidpin extending into and resiliently held inengagement with thesaidsup.- port |09 by means of a L'J-shaped bend. |724 placed in the other end portion ofthe said pin. the free;

arm of said U-shape abutting against the inner side of the adjacent arm |23 thereby exerting a resilient force on said pin tending to movethe` same into engagement with said support... It

may be here pointed .out that the frame of the.

machine, of which the support |09 is part,l provides one side of the electric circuit for operating the gage mechanism and the stop motion'rnecha- Member 22 is provided. with inclinededges. |21 in theform of a V whichV4 nism .of the machine.

extend to a slot |28 of a size4 such that when the silk is of proper size friction will be; exerted on the opposite sides of this sllot |2f8`and will rock this member |22 on its pivotv pin |24v so thatiits lower portion |29 will be spaced from a contact |30 which extends through the block ||0 and is in electrical connection with the wire |3 I When the thread. |02 gets belowsize, the member;y |22 swings to complete this electrical connectionand will actuate mechanism to be hereinafter described to cause the filament o f another cocoon to. be supplied to the. thread. y

An auxiliary manually operatedadditioniilament supp-lying device is providedin the form of ears |32 extending from the bracket |33which is in electrical connection with thewire |3| and which pivotally mounts a. bell crank wire |34` having an end |35 which may swing intoengagement with the body |09 to complete the electrical connection of wire |3I shouldl it be desired to manually actuate said mechanism to add laments to make up the size of the thread.

The body |09 is provided with a pivotal mounting |40 which pivotally mounts arm |4| -upon which the guide roll |0 islrotatably positioned. This armv |4I Ais limited in its upward movement by a pin |43 but will swing'downwardly upon breaking or slackening of the thread, transferring motion to arm |44 which is connected thereto to cause the cylindrical member |45 of insulating material on theend of this arm |44 to rise and swing the plate |45` about. itspivot .so that a pivoted rocker |52 which-is' supported bythe core |53 may swing downwardly `due to thesame being weightedas Aal1-|50 and cause-the spool `|01 to be lifted bythe upwardswing lof the arm .|55 of the rocker |52, asshown in Fig.15.- .This.will. raise the conical.clutch..|5fromthe;.

The block||0 is recesse'dasxat |2| totV receive a gage member designated generallyV 7 cone |51 which lis "continuously driven by pulley |64 for reeling the silk. YThe rocker |52 (see Figs. 14 and 17) is pivotally mounted as at |68 on a bracket |6| xed on the upper horizontal cross beam |62. The said rocker is made of wire bent into a general U-shape providing .the arm |55 which extends to be moved into engagement with the bottom of spool |81 and an arm |58 provided with a right angular handle |59 at the free en=d thereof. These arms |55, |58 are pro-` vided with a coil therein intermediate the ends thereof which provide aligned openings for receiving the said pivot |60. A strap is supported on the arms |55, |58 adjacent the bight of the rocker |52 and there is mounted on this strap mercury switches |63, one of which is in the circuit of the solenoid and is moved to openposition upon the downward swing of said rocker |52 to interrupt the circuit to the said solenoid |5| after the same has been actuated to withdraw its core |53 from engagementwith the bight of the said rocker |52. The other of said mercury switches |63 is for a similar function lin the circuit of another solenoid to be herein described. If it is desired, the clutch |56 may be manually disconnected by an upward movement of the arm |58. To reset the machine in operation at this point, the handle |59 is manually moved downwardly to swing the other end of the rocker upwardly past the core |53, which may be manually pushed inwardly for this purpose and then released, to be in position to support the rocker |52 in the raised position to permit engagement of the spool |81 with the cone |51 and to close the circuits of the said solenoid at the mercury switches |63.

In the event that either stretch of the yarn extending to the guide 95 andV the .guide H5 becomes broken, it will cease to pull downwardly on the guide 95 andthe arm 96 which is weighted as at 98 will swing downwardly about its pivot 91 and the weight 98 will engage and swing the plate |46 into engagement with the contact |88 and close the circuit to the solenoid |5| to energize the same towithdraw its core |53 to permit the said rocker |52 to swing, as previously described, todeclutch the spool |81.

In order that the thread may traverse on the spool |81 I have mounted a glass rod |18 upon the traverse bar |86 at a location in front of each of the spools 81. This glass rod |18 is bound to the traverse bar |86 by a clamp designated |1| and shown more particularly in Figs. 2 and 3. This glass rod |18 extends upwardly as at |12 so as to prevent the thread from traversing upon this end of the rod while the clamp will prevent the thread from traversing in the other direction along the rod |18 to an excessive extent. The traverse bar |86 is mounted at the end of a lever |13 which is pivoted at mi in the on shaft |86 which extends throughout the length of the machine. A spiral gear |81 on'shaft |08- drives spiral gear |88 on shaft |89 which also extends throughout the length of the machine and from these two shafts |86 and |89 power is de`' rived for operating the various mechanisms of the individual units. The traverse motion is also ing when the apparatus is in operation a round g. common to all of the units and is driven from the opposite end of the machine wherein there is provided a gear |98 meshing with gear |9| in suitable bearings |92 to drive shaft |18 upon which shaft the cam |11 is mounted for reciprocating the traverse motion which is common to all the units. The drive for the spindles upon which the bobbins |81 are mounted is also common to all of the units and is taken from the same end of the machine as is the traverse motion. In this case Ythere is a pulley |95 (see Fig. 1) which through belt' |96 drives pulley |91, to which there is fixed the pulleye|98 and abouty which there extends the round belt |99 extending upwardly over the two pulleys 288 and 28| (see Fig. 16) and from which this belt travels overguide pulleys 282 and 283 and contacts each of the pulleys |64, the same being tensioned by idlers 288 in between these pulleys |64 for each of the spindles. The two pulleys 288 and 28| are loosely mounted upon shaft 285 at the upper end of arm 286 (see Fig.,1) which is pivotally supported as at 281 `from the upright support |3 and which is tensioned by spring288 extending from arm 289 which is adjustably held as at 2 I8 on the upright support |3.

The drives for shafts 25, 56 and 2|8 are individual for each unit and are taken from the shaftv |86 by means of a clutch 234 to be hereinafterrdescribed. There is one such clutch for Veach unit which is held normally stationary, as

will hereinafter appear. The clutch 234 carries a sprocket gear 2 I5 rotatable therewith and which is connected by means of a sprocket chain 2|6 to rotate a sprocket gear 2|1 fixed on shaft 218 on which is mountedthe drum 1|, there being a shaft 2 8,. for each unit. A sprocket gear 2|9 is fixed to the shaft 2 B and drives a sprocket chain 228 which extends to sprocket gear 22| on the end of shaft 25 .to drive this shaft and also the pulley roll 26 which is mounted thereon. At the opposite end of this shaft there is provided a sprocket 222 driving sprocket chain 223 which extends upwardly to drive shaft 56 upon which the cone 55 is mounted.

From the shaft |89 which is continuously rotatbelt 225 extends about the drum 226 to drive the pulley 98-on the shaft 86 by engaging the groove 9| thereof.

Theclutch 234 herein shown (see Figs. 8, 9 and 10) comprises a cylindrical body 245 having a recess 246 extending inwardly and radially from the periphery thereof, and a shank 241. This body is` mounted on the shaft |86 for free rotation thereon. The sprocket gear 2|5 is mounted on this shank 241 for rotation therewith. A pawllike member 233 made of flat stock and extending generally on the curvature of the body 245 is pivotally mounted intermediate the ends thereof on the body 245 as at 248 and extends generally along the periphery of said body 245. One end of the member 233 on one side of the :pivot 248 has a right angularly extending finger 235 which extendsy into said recess 246. A compression spring 231 carried by the body 245 at a location to engagethe'member 233 on the other'side of the pivot 246 tends to swing said member about said pivot to move said finger 235 inwardly into the said recess 246, as shown in Fig. 10. There is `also mounted on the shaft |86 for rotation thereof a collar 249'. A collar` 258 is fixed to the shaft y|86 and a'flatwasherspring 25| is interposed between said collar and the free end of the shank 241 and. tends to move said body toward said collar 249.

The finger 235 is .of a Width (see Fig. to= extendv in* overlapping relation with said wheel 23E and under thel vforce of said spring 231 isv moved into lengagement with theteeth of said wheel 236, thus connecting said ratchet wheel 236 to said shaft for rotation therewith. However, the clutch is normally lheld in the declutched relation by means of a solenoid 23| which is mounted at a location so that its core 232 when atthe outward position vWill overlie and engage that portion, of the member 233 on the side. of the pivot thereof to hold said nger in the raised .position and out of engagement `with -thef teeth of the Wheel 236, there being suiiicient frictional engage-y ment between said core and member 23S-to Iprevent free rotation thereof on said shaft |85. Upon energizing of the'saidzsolenoid 23|,.s1-1ch'as` by closing of the electrical circuit thereof at Contact |30 or through contact manually made by wire |34, the core 232 will be drawn within the solenoid windings to free member 233 to be moved by the spring 231 to swing the finger 235 inwardly into engagement with the teeth of the wheel 236 to clutch the said gear 2|5 with the shaft |85, as previously described. The other mercury switch |63,previously referred to, is inthe circuit oi ythis solenoid 23| and operates as previously described in the branch circuit of the solenoid 23| .to open the same upon the movementv of said rocker |52 in the direction to declutch the spool |1| so that no current will flow through said solenoids when the apparatus is not reeling yarn. The opening of this said branch of the circuitvwill de-energize the solenoid23| and itscore will return in a usual manner (not shown) to-` the outward position thereof. The wheel 235l and body 245 will now move as a unit and through gear 2|5 will drive such mechanism asis connected therewith, as previously described. In the-rotation of body 245 the advancing end of the member 233 will ride beneath thecore 232 to be engaged thereby to move the said memberv233 against the action of the spring 231 to swing the said` lingerv 235 out of engagement with the wheel 235 and. thusdeclutch the gear 2 |5 from the shaftl |8610. arrest the motion or the different parts driven thereby, It will now be apparent that the clutch 234 is intermittently operated in responseY to the condition of yarn, whether the` sameV be broken or require additional filaments, as above described.

.In operation the group' of ilaments 92 are drawn from ,the cocoons'4 in the reeling basin I6 over guide 10 and through the hollow shaft 85. Thence as shown in Fig: 1 the thread extends. in the usual loop knownin silk reelingv up tothe bobbin or spool:` |01. Should any'onewof the filaments 92 fail thus making the sthread smaller in size,l the gage member. |22 will swing on its pivot to engage, the electrical contact |30 to close the electric circuit of solenoid 23|. The circuit of the apparatus includes the control box shown in Fig. 1 and designated generally 230.

;The closing of said circuit of solenoid 23| will through means in said control box energize the solenoid 23| to Withdraw the core 232 to permit the clutching of gear 2|5 with the shaft |86 whereby the parts driven through this gear 2|5 will be set into motion. Upon the clutching of the gear 2|5, motion therefrom will be trans- .-by the said gear 2|5.

10 mitted, as previouslyA described, to the shafts 25, .56 and 2|8 and set-into motion such parts as described and operated thereby to effect the discharge of a cocoon into the basin I6 and for its filament attached to the cone 55 to be positioned ata location to be engaged by an arm 8| of the 'continuouslyrotating member 80 to wrap said filament abouti those projecting'through the shaft 86. 'Ihe timingis Asuch that the added filament will be carried -to the .gagejust prior to `the clutch: 234 completing a revolution.

'Should' the added filament Ybe insuflicient to buildtheyarnto 'the requiredv size, the gage |22 will remain inengagement with contact |30 to maintain .the circuit Aclosedfor another revolution `ofthe clutch,234 for another cocoon to .be cast onthe. yarn,v aspreviously described. Upon the yarn being` brought to the required thickness .or-size, thefmember |22 will. be moved thereby o utof engagement-With'contact |30 to open the circuit at said. Contact |30 topermit de-energizing of :solenoid 23| and thereby permitting saidclutch.- 234 to.: declutch the gear 2|5 from shaft |86,y thus bringing to rest such parts driven The pickup wheel is constantlyrevolving but should the hand engage this wheel because of its light frictional drive the Iwheel wouldstop'. and the same may bev'grasped-and Withdrawn from the shaft 8B for cleaning the same if desired. As the cocoons vare exhausted fromthe supply chamber the operator will add new 'cocoons andwrap the filaments from each cocoon around the cone 55; Should the thread'break thearm 96 will rock to close contact Mfandfwill energize the sole- 'noid I5Iv to lift the spoolv |01. to declutch the same and thus -stop the driveof the spool from the constantly, driven belt which drives the other spools ofthe apparatus. Thesame stopping of the operation ofi the Aspools may be caused by the dropping .of pulley A|04 which similarly actuates the stop control.
